Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multi-layer gateways are added for connection migration during network switching, then connection reliability is improved, but data packet latency increases and server burden increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoiddata packet latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the machine room identifier information from the connection identifier in the data packet header, allowing the terminal to directly identify and connect to the target communication machine room without passing through multiple gateway layers. This extraction of key routing information enables direct connection establishment, resolving the latency issue while maintaining connection reliability through proper identifier-based routing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of having gateways forward packets through multiple layers, the patent inverts the approach by embedding the target machine room identifier directly in the packet, enabling the terminal to initiate direct connection to the target machine room. This inversion eliminates the traditional gateway-mediated path and reduces latency while maintaining reliable connectivity.

Inventive Principle:

Principle #13The other way round (Inversion)

2Stability of the object's composition

If multi-layer gateways are used for stream pulling, then connection stability is improved, but the number of unpacking operations increases and server resources are consumed

Engineering Contradiction:

Improveconnection stabilityVSAvoidserver processing efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The patent extracts the machine room identifier from the connection identifier in the data packet, enabling direct routing to the target communication machine room. This eliminates the need for multiple gateway unpacking operations, reducing server processing burden while maintaining connection stability through proper identifier-based routing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The terminal device performs self-service by using the embedded machine room identifier to directly establish connections with the target communication machine room without requiring gateway mediation. This self-service approach eliminates unnecessary unpacking operations at intermediate gateways, improving server efficiency while maintaining stable connections.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If seven-layer load-balanced gateway and four-layer gateway are added, then connection migration capability is improved, but device complexity and hardware costs increase

Engineering Contradiction:

Improveconnection migration capabilityVSAvoidgateway structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the machine room identifier information from the connection identifier, enabling direct routing to the target communication machine room. This eliminates the need for complex multi-layer gateway structures (seven-layer load-balanced gateway and four-layer gateway), reducing device complexity and hardware costs while maintaining connection migration capability through identifier-based direct routing.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent inverts the traditional gateway-mediated connection migration approach by embedding the target machine room identifier in the data packet, allowing the terminal to directly establish connections during network switching. This inversion eliminates the need for complex gateway infrastructure while preserving connection migration adaptability.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Disclosed are a video stream data acquisition method and apparatus. An implementation of the method includes: determining, in response to receiving a stream pulling data packet from a target terminal, whether a machine room identifier of a communication machine room that receives the stream pulling data packet is the same as a target machine room identifier included in the stream pulling data packet, where the stream pulling data packet is generated during the target terminal's playing of a video stream, and the target machine room identifier is a machine room identifier of a communication machine room that receives a first stream pulling data packet first generated when the target terminal is playing the video stream; if not, forwarding the stream pulling data packet to a target communication machine room corresponding to the target machine room identifier; and acquiring video stream data through the target communication machine room.
